1997年底日本Nishizawa等首次从输血后非甲 庚型肝炎病人血清中分离到一种新的DNA病毒 ,暂命名为TT病毒 (TTV) ,并认为TTV可能与非甲 庚型肝炎有关。本文对TTV的病原学、流行病学及其与肝病的关系等方面的研究近况作一综述。
At the end of 1997, Japan’s Nishizawa et al. First isolated a new type of DNA virus from blood serum of non-Hepatitis A patients after transfusion and was tentatively named as TT virus (TTV). TTV may be related to non-Hepatitis G virus. In this paper, the etiology and epidemiology of TTV and its relationship with liver disease are reviewed.
